Dye Lot Tips

• •Always buy all skeins from the same dye lot number at once.
• •Check dye lot numbers before leaving the store — they are printed on the label.
• •If you must mix dye lots, alternate rows between skeins to blend the transition.
• •Buy at least one extra skein beyond the calculated amount for swatching.
• •Store leftover yarn with the project label for future repairs.
• •Hand-dyed yarns can vary significantly even within the same batch.
• •When substituting yarns, match both yardage per skein AND weight (e.g., 50g vs 100g).

How to Use

1. Enter the total yardage required by your pattern.
2. Enter the yardage per skein (found on the yarn label).
3. Adjust the safety margin slider — 10-20% is recommended for most projects.
4. The calculator shows exactly how many skeins to buy from the same dye lot.
5. Always verify the dye lot number matches on every skein before purchasing.
